Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518646, here are decompositions:
- 53 + 31518593 = 31518646
- 179 + 31518467 = 31518646
- 293 + 31518353 = 31518646
- 317 + 31518329 = 31518646
- 359 + 31518287 = 31518646
- 449 + 31518197 = 31518646
- 557 + 31518089 = 31518646
- 647 + 31517999 = 31518646
Showing the first eight; more decompositions exist.
